'Important' in the Bible

So whoever breaks one of the least [important] of these commandments, and teaches others to do the same, will be called least [important] in the kingdom of heaven; but whoever practices and teaches them, he will be called great in the kingdom of heaven.

“Teacher, which is the greatest commandment in the Law?”

This is the first and greatest commandment.

“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you give a tenth (tithe) of your mint and dill and cumin [focusing on minor matters], and have neglected the weightier [more important moral and spiritual] provisions of the Law: justice and mercy and faithfulness; but these are the [primary] things you ought to have done without neglecting the others.
